Wrinkly skin syndrome
Overview
A very rare genetic disorder characterized by wrinkly skin that occurs primarily on the palms and soles but can occur on other parts of the body. The condition is also associated with various other abnormalities.
Symptoms
* Growth retardation * Wrinkled skin * Mental retardation * Hypotonia * Small birth weight
Causes
* Dry skin is a very common problem –Low humidity and cold temperatures make winter xerosis and “winter itch” common complaints –Mild xerosis can cause impaired skin barrier function and allow irritants and allergens to more easily affect the skin –Most common on the legs, but often affecting the entire skin surface –Can present with severe pruritus without much evidence of a rash * Severe xerosis is common in the elderly, and can cause eczema craquelé –Patient's legs often have scale that resembles cracked porcelain –Secondary erythema and excoriations occur because of the persistent itch * Ichthyoses vulgaris –Very common cause of dry skin –A genetic defect in skin barrier function, leading to a higher risk of atopic dermatitis –Patients often have hyperlinearity of their palmar skin and xerotic fish scale on their legs * Many genetic conditions, such as the large family of ichthyoses (including X-linked ichthyoses, Netherton's disease), lead to severely dry skin in association with other systemic manifestations * Hypothyroidism and hyperthyroidism can also cause marked xerosis and/or itch * Anemia * There is an uncommon association between lymphoma and marked xerosis * HIV * Sarcoidosis * Liver and biliary disease, and renal insufficiency, are commonly associated with xerosis and marked pruritus * Diabetes mellitus * Medications (e.g., niacinamide) * Atopic dermatitis
